Re: [usocket-devel] [usocket-cvs] r553 - in usocket/trunk: . backend vendor

Hi Chun, I think the JDI stuff I added way back when, isn't needed anymore. You could try removing it. Before, it wasn't always possible to dynamically determine retrieve a method from a JavaObject. Now, since it has an IntendedClass slot, the information that JDI was trying to capture, has been added to the base JavaObject class. If you want, I can help to phase out JDI. With kind regards, Erik.
